Hi @marcoyee,

It appears that your `connnect3.out` binary is using SQLCipher version 3.4.1 based on the output. Prior to SQLCipher version 4, `HMAC_SHA512` and `PBKDF2_HMAC_SHA512` was not supported within the library. You should consider rebuilding the SQLCipher library with the latest version, then link that into your application to support the 4.x features.
